To all whom it may concern. 7

tie it known that T llnnnnn'r (l.- Umvnn, a ciiizer oi the United States. and a resi dent oil the city of ile'w' York, borougl'i o t l -xiruiliae in the coin and i tate (it New Yorlz, have invented certain new and usc'tul lniprorcmcnts in Reels For Photographic l-ihns, o'li' r-rhich the Following is a tull, clear, and exact description.

Among the principal. objects which the present invention has in view are: To strengthen the construction; to simplify the repair thereof in. the event of damage thereto: to ventilate the lilm when held within the reel; to sinipli'iy the method oil? holding the end-ct ribbon or film in the reel tor re-winding; and to simplify and cheapen the construction.

Description.

lieretoi ore the rolls of photographic [ihn have been carried on reels or spools preferably constructed, from sheet metal. mounted upon a central core. The reels have been necessarily light, and subject to injury such as that of being crushed out of shape when lying on the floor after being emptied of the film. The metal from which these reels are constructed is made ligl'it to save the weight thereof, which becomes a serious factor in the transportation or transshipment of the films.

To avoid the dilliculty referred to, I have constructed reels from stout wire, employing continuous rings 9, which are rigidly connected to the terminals of the extensions of U-shaped members 10. The members 10 are radially disposed with reference to the rings 9, and the cross members 11 of the members 10 are held in spaced relation by check pieces, or discs 12. The edges of the discs 12 are recessed to receive the cross pieces 11, as shown best in Figure 1 of the drawings.

To strengthen the, construction small wire rings 13 are rigidly attached to the cross membe s'il either by welding or soldering the ring and members where the same ongage or by any other-suitable and practicablemeans. The rings 13 also act as stop members for regulating the position of the discs '12. which, as shown in Figure 2 of the drawings. are pressed closely on the said rings. The discs 12 are held in service position by the tube 1.4:. The tube 14:, as shown best in Figure 3 of the drawings, has an oilsct lreyway 15, pressed therein to align with the key formed on the winding mandrel for reels of this character.

The extremities of the tube 14- are overturned to form the rivet heads 16. When the heads 16 are overturned on the said discs 12, the said discs are held rigidly in position.

To form the body of the spool or drum on which the reel is wound, I employ a section of spring metal 17. (hie cud ofthe section 17 is bent to form a hook. 18, the extremity whereof forms, with the body of the section 17, a throat, contracted to a dimension slighth less than the thickness of the mem ber 11. This servesto ho d the section 17 in its relation to thereel at all times.

The opposite end of thosection 17, is

shaped to torin the clasp end 19, which con forms with the book 18, to co-operatetherewith for holding the inner end of the film when the same is being wound thereon.

As shown by dotted lines in Figure 3 of the drawings, the clasp 19 may be pressed out of engagement with the hook 18 by pressure applied on thesection 17 which, when released. resumes its service position, shown by the full lines in said figure. engaging in holding relation the end of the film between the said end 19 and book 18.

The skeleton form in which the reel is constructed allows for the use of material. having great strength, without exceeding the established limit of weight in the completed reel. If perchance the reel should, be crushed the diiiicultyin making the repair is materially lessened, due to the reason that all that in all probability would be injured would be the members 10. The members 10 would be bent together. This would merely require the exercise of suflicient strength to pull them apart to their original shape or dimensions. the central structure forming the drum on which the reel would be Wound is practically indestructible.
